Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and more specifically, particularly relates to laser composite welding equipment for single-sided welding and double-sided forming of carbon steel without groove making. Background Art

[0002] When welding carbon steel workpieces, in order to ensure the quality and efficiency of welding, laser hybrid welding equipment is generally used for welding operations. Laser hybrid welding equipment combines the advantages of laser welding and traditional welding technology. Laser hybrid welding equipment not only uses laser as a heat source, but also combines other welding methods (such as arc welding). For carbon steel materials, traditional welding methods often require pre-processing of grooves to prepare for welding, but laser hybrid welding equipment uses special welding technology and parameter settings, which can achieve single-sided welding and double-sided forming without beveling, greatly simplifying the preparation work before welding.

[0003] The existing application number is: CN201611097489.4. The present invention discloses a laser hybrid welding device, including an operating table for welding, a shock absorbing device is provided at the lower end of the operating table, a conveying device for transmitting the workpiece to be welded is provided at the middle of the upper end of the operating table, a plurality of workpiece clamping mechanisms are provided on the conveying device, two mutually parallel support rods are provided on both sides of the conveying device, a connecting block is fixed at the upper end of the support rod, a moving mechanism is provided on the two connecting blocks, a fixing device is provided on the moving mechanism, and a welding device is provided on the fixing device. The present invention realizes the automatic conveying and clamping of the workpiece by combining the conveying device and the clamping device, and the combination of the second electric slide rail, the first cylinder, the third driving device and the moving mechanism realizes the three-dimensional movement of the laser welding gun and the arc welding gun, which not only improves the welding efficiency, but also expands the application scope of the laser hybrid welding, and is suitable for promotion.

[0004] Based on the above, when the existing laser hybrid welding equipment is welding a carbon steel workpiece, since the surface of the workpiece is hot after welding, it is necessary to wait for the workpiece to cool down before the workpiece can be disassembled and then replaced with a new workpiece that needs to be welded. This causes the laser hybrid welding equipment to be idle for a long time, affecting the welding efficiency of the carbon steel workpiece. Utility Model Content
